There is nothing good about it from an environmental standpoint, and coal contains way to much ash to be used as a liquid fuel substitute.

Abstract: A method of preparing new compositions of stabilized suspensoids of hybrid fuel oils comprising varying mixtures of ultrafine coal, virus-size pure carbon particles, finely ground newsprint and sawdust. The resultant stabilized fuel slurries are mixed mechanically to produce pumpable new forms of fuels whereby conventionally available petroleum fuel oils can be extended.
